What factors decide to which faces we are attracted

Iam Sample researched what factors decide to which faces we are attracted: “when it came to rating people as hot or not, even identical twins who grew up together disagreed. In fact, genetics turned out to explain only a fifth of the variation in people’s tastes, meaning very little was inherited. The greatest influence on people’s preferences was their own life experiences – a mass of factors that could include the friends they make, the odd chance encounter, and even the face of their first love.”
